tried to install RC4 on a 800mHz Athlon machine with 512mB Ram. Everything went fine until the very end, when being asked to restart the system. Screen gets messed up and Computer remained frozen. Upon powering down and restarting the boot goes multiuser, gives me a "setting up message bus FAILED" and hangs at setting up hald position. After a while I get a terminal login prompt. I can login but I can't start the x server. I reproduced this behaviour twice. I am not Linux savvy enough to troubleshoot myself.

On my 1.3 Ghz Celeron, YouTube and Flash videos played in Opera are jerky. About every 10 seconds there will be a short pause, which makes it difficult to watch a video. I played a YouTube video directly from youtube.com on Firefox and there were no pauses or choppiness. I had attributed the problem to the low specs of the computer compared with the 64-bit dual core computers, but I now realize that's not so because YouTube and Flash videos under Firefox were okay.

I don't know what happens on the 64-bit computers, as I haven't played many videos. Will have to try some and see if Opera has the same problem there.--GrannyGeek
